Specification of Letters Patent.

Patented Jan. 4, 1916.

Application filed July '7, 1914. SeriaT No. 850,824.

To all whom it may concern:

Be it known that I, ROY H. MORRIS, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia have invented a "certain new and useful Improvement in Stopsfor Talking-Machines, of which the following is .a specification.

. My invention relates for talking machines of the disk type, and hasfor one of its objects to provide astop mechanism in which the point ofstopping 'of the turntable when the record carried thereby has beenreproduced, may be previously and accurately determined and in which theactuation of the stop ispositive and precisely in accordance with thepoint predetermined.

Another object of thisinvention" is to provide a simple and effectivestop, which imay be quickly attached, to a talkingmachine and which iscontrolled by mechanism connected with the motor.

WVith these and other objects in view, this invention consists of thefeatures, details of construction and combination of'parts described inconnection with the accompanying. drawing and thenmore"particularlypointed out in the claims.

In the drawing, Figure'l, is a plan View of the stop containing'housingshowing the indicator. Fig. 2, is a plan view showing the indicatingface of the housing, the stop being shown partly in dotted lines. Fig. 3is a sectional elevation on lines 33, Fig. 2, showing the stop mechanismand the motor controlled means for actuating the stop, and

Fig. 4, is an elevation of the stop actuating.

and indicating member.

The invention consists preferably of an annular housing 1, havingcentrally thereof a hollow stem 2, arranged to extend through the top 3,of a talking machine, and being threaded at its end to receive a nut 4,whereby the housing may be firmly secured'to the,

said top 3. A portion of said hollow stem 2, extends into the housing 1,as shown at 5, and this portion forms a bearing for a stopcarryingmember 6, in the longer end 7, of which is slidably mounted a plug 8,having a socket 9, for receiving a tension spring 10, which normallyholds said plug projected and the shoulder 11, thereof in engagementwith a lip 12, formed on said carrying member 6. Said spring 10, is heldinposition.

by a pin 10, extending transversely of said,

to an automatic stop carrying member 6. The plug 8, is pro vided with anadjustable stop 13,having, a rubber or other suitable facing 14, forengagement with the periphery of a turntable 15, of a talking machine.The adjustment of said stop 13, may be effected in any suitable manner,as by a threaded stem 18 on said stop' 13,-engaging a threaded orificein said plug 8, asuitable lock nut 16, beingprovided to lock said stopin position of adjustment. A portion of the wall of said housing 1,adjacent the turntable 15, is cut away as at 17, to permit the stop 13,to project therethrough and engage the turntable. Ro-

tatably mounted on said hollow stem 2, is a I plate 20, having ashaft21, extending for a short distance above the level of said plate andthrough sald hSllow stem 2. Said plate 20, is of smaller diameter thanand fits in an opening 19,in' said housing, forthe purpose of leavingaspace between said table and'opening. Loosely fitting over that portionof saids haft which extends above,'an'd resting on said plate 20,is aweight 22, having an arm 23, which extends downwardly into the housing,and an indicator 24, ex-

tending outwardly from i said member 22, over the face of the dial orindicating marks on the face o'fthe housing. The arm 23, of the member22, is so arranged that it will pass the shorter end 25, of saidstopcarrying member 6, but will engage the longer end 7 and bring the stop13, in contact with said turntable. On the end of said shaft2l, is

a bevelpinion 26, to which power, is transinitted fromthe motor 27, of atalking machine,"through a train of reducing gears 28, of either thetooth or friction type as desired. a

The face of said housing is inscribed with suitable indicating marks,preferably con secutively arranged, as shown in Fig. 2,

these marks inv this instance consisting of a series 29, of outsideletters, runnlng from A to N, and a series 30 of inside letters,

running from N to A. The inside series of letters are provided todetermine the length of the record, while the outside series is used toset the indicatorfor actuation of the stop upon completion of thereproduction of the record. Thus to determine the length of a record,the indicator 24, is set on the line marked A of the inside series 30,and the turntable then setin motion. When the reproductionof the recordis completed, the indicator will have traveled over the face A of theoutside series.

of the housing and will be stopped in its travel with the stopping ofthe turntable. The designation on the face of the housing at which theindicator has stopped is then by preference, noted on the face of therecord. so that any user mav set the stop in accordance with the legendcontained on each record thus marked. For instance if the indicator hasstopped at F on the inside series 30, such F is marked on the record.The corresponding F of the outside series 29, is then the point at whichthe indicator must be set to cause the arm 23, to actuate the stop whenthe record is completed, and when the indicator reaches the line markedAssuming, therefore, that the indicator 24, has been set at F on theoutside series 29, and that the motor .is set in motion, the weight 22,will revolve with the plate 20, and the arm 23, on said weight, willengage and move the, stop carrying member 6, and bring the stop 13, inengagement with the periphery of the turn table upon the completion ofthe reproduction of a record. Such operation of the stop carrying member6, will occur irrespective of the position it occupies in the housing,that is to say, the stop carrying member ,may be moved by the arm forthe entire distance of the travel of said arm, or it may be moved for adistance suificient only to cause slight contact of the stop 13, withthe turn table, which frictionally brings the stop carrying member tooperative position.

In order to insure the actuation of the stop at the proper time and tocompensate for the wear of the rubber or other facing 14, the arm 23,may be provided with an adjustment in the nature of a screw 31, whichmay be used to cause an earlier or later actuation of the stop than thatpredetermined. To limit the movement of the stop-carrying member 6,about its axis, a suitable lug 32, may be provided, as shown.

What I claim is 1. In combination with the turntable and motor of atalking machine, a housing having a series of indicating marks, an opening therein, and a hollow stem, a stop carrying member on said stem, ashaft extending through said stem, means to transmit power from themotor to said shaft, and a member on said plate having an indicatoroperable over the face of said housing, and an arm depending from saidmember to operate said stop carrying member.

2. A brake for a talking machine, comprising a housing having a hollowstem arranged to extend through the top of a talking machine, a portionof said stem extending within said housing, a stop carrving member insaid housing and loosely mounted on said stem, a shaft extending throughsaid stem, means to transmit power from the motor of a talking machineto said shaft, a plate on said shaft and resting on said stem, a Weighton said plate having an indicator, and a means on said Weight foractuating said stop carrying member.

3. A brake for a talking machine, comprising a housing having an openingin the top and side thereof, and indicating marks on the top, andprovided with a stem arranged to extend through the top of a talkingmachine, a portion of said stem extending within said housing, a memberwithin said housing and loosely mounted on said stem, a stop carried bvsaid member for engaging the turntable of a talking machine, a shaftextending through said stem and having operative connection with themotor of a talking machine, a table on said shaft and resting on saidstem, and a weight loosely mounted on said table and provided with anindicator and an operating arm for said stop carrying member.

In testimony whereof I afiix my signature in the presence of twowitnesses.
